When a patch adds a local version to a package, the SBOM reported the resolved upstream version rather than the version of the wheel it was embedded in, so the SBOM failed to identify its own wheel and vulnerability scanners could draw wrong conclusions.

Pass the version parsed from the wheel filename to generate_sbom() as wheel_version. The downstream purl, wheel package entry, and document identity now use the actual wheel version (including local versions) automatically, without requiring a per-package purl.version override. The upstream package entry still identifies the resolved source release, and an explicit purl.version override continues to take precedence.

Fixes: #1375

Walkthrough

generate_sbom accepts an optional wheel_version. When provided, the downstream package purl and document identity use this value, while the upstream package continues to use the resolved version. The wheel metadata path passes the version parsed from the wheel filename. Added tests cover locally versioned wheels, explicit purl.version overrides, and SPDX 2.3 validation.

Explanation

[#1375] requires the embedded SBOM to identify the built wheel when its version differs from the resolved upstream version. The diff at head matches this requirement. In src/fromager/sbom.py, generate_sbom() accepts wheel_version: Version | None = None. The downstream purl version and document version use wheel_version or version. The upstream package entry still uses version. In src/fromager/wheels.py, add_extra_metadata_to_wheels() passes dist_version, parsed from the wheel filename, as wheel_version. An explicit purl.version override still takes precedence through the existing _build_downstream_purl() path. tests/test_sbom.py adds two tests. The first asserts that wheel_version 0.5.5+local.1 produces the document name test-pkg-0.5.5+local.1, the wheel versionInfo, the purl pkg:pypi/test-pkg@0.5.5%2Blocal.1, and the upstream version 0.5.5 with purl pkg:pypi/test-pkg@0.5.5. The second asserts that a purl.version override of 0.5.5+corp.1 wins over the wheel version. Both tests validate SPDX 2.3. Per the change summary, tests/test_wheels.py covers the add_extra_metadata_to_wheels() call site with a local version. I did not inspect that test file. The verdict does not depend on it, because the call-site change is confirmed in the diff. I did not run the test suite.

Full details: Out of Scope Changes check

Explanation

The source changes are limited to the SBOM version selection in src/fromager/sbom.py and the single call-site argument in src/fromager/wheels.py. Both support [#1375]. The docstring update in src/fromager/sbom.py describes the new parameter. The PurlConfig.version documentation change in src/fromager/packagesettings/_models.py, per the change summary, corrects the default that this change alters. The added tests in tests/test_sbom.py and tests/test_wheels.py verify the required behavior and the upstream and override precedence rules. No unrelated change is demonstrated. I did not inspect the _models.py and tests/test_wheels.py diffs directly. Their scope rests on the change summary.

tests/test_sbom.py: 1

Add a differing-version case to the wheel SBOM test.

test_add_extra_metadata_generates_sbom_when_enabled in tests/test_wheels.py uses Requirement("test_pkg==1.0.0"), Version("1.0.0"), and the wheel test_pkg-1.0.0-py3-none-any.whl. The wheel and resolved versions match. The test asserts only that sboms/fromager.spdx.json is written.

src/fromager/wheels.py:326 passes wheel_version=dist_version to sbom.generate_sbom(). Reverting that argument to version still passes this test. The direct generate_sbom tests in tests/test_sbom.py set wheel_version themselves, so they do not reach this call.

Use a wheel filename with a local version, such as test_pkg-1.0.0+local.1-py3-none-any.whl, and keep the resolved version at 1.0.0. Then assert that the SBOM document name, the wheel package versionInfo, and the purl use 1.0.0+local.1. The purl should encode the plus sign as %2B. Assert that the upstream package entry keeps 1.0.0. Read the generated SBOM content, not only the file path.

@rd4398 the fix looks right, two things before merging:

• The wheels.py call site isn't covered by any test: changing wheel_version=dist_version to wheel_version=None still passes all of test_sbom.py and test_wheels.py. Please add a test that runs add_extra_metadata_to_wheels() on a wheel with a local version (e.g. 1.0.0+local.1 with resolved version 1.0.0) and checks the generated SBOM content.
• The PurlConfig.version docstring still says it defaults to the resolved version. Please update it (and the docs generated from it) to say it defaults to the wheel version, with a versionchanged note.

Thanks for the feedback @mprpic. The latest commit that I have pushed fixes both the points

rebase

❌ This pull request comes from a fork and cannot be rebased

Details

GitHub refuses an OAuth token on its rebase API for a fork, so rebasing one means impersonating a GitHub user to force-push the contributor's branch. Mergify does not do that.

Use the update action or the @mergifyio update command instead: it brings the pull request up to date by merging the base branch into it, and needs no impersonation. It only has something to do when the pull request is behind its base branch, so if what the branch needs is a linear history, its author has to rebase it themselves.

[mergify]

queue

⚠️ Configuration not compatible with a branch protection setting

Details

The branch protection of main requires branches to be up to date before merging. The merge queue tests pull requests in a draft PR built on the latest base branch, then merges the original pull requests. Their own branches were not updated with that base branch, so GitHub considers them out of date and refuses to merge them.

To fix it, turn off Require branches to be up to date before merging in the branch protection of main. It is safe to turn off: the merge queue already tests every pull request it merges on the latest base branch, together with the ones queued ahead of it. That is what this setting checks. Changing the setting needs admin access.

If you need to keep the setting:

• Use merge_method: fast-forward: the queue pushes the tested draft PR's branch to the base branch itself, which the setting does not refuse.
• Use in-place checks: Mergify tests each pull request on its own branch, one at a time, which gives up parallel checks and batches. To do so, set merge_queue.max_parallel_checks: 1 and merge_queue.mode: serial, set every queue rule batch_size: 1 and max_checks_retries: 0, and avoid two-step CI (make merge_conditions identical to queue_conditions).
